Enceladus Has Potentially Life-Giving Hydrothermal Activity

Saturn's icy moon Enceladus is showing definite signs of hydrothermal activity -- similar activity that is found along deep sea vents on Earth where water is heated and minerals are formed.

Enceladus' famous plumes are known to be composed of salty water vapor laced with organic compounds, an indication that a sub-surface liquid water reservoir is being heated and blasted through cracks in the moon's icy crust. Now, rock particles have also been discovered, leading to the possibility of hydrothermal activity near the moon's core. | NASA/JPL-Caltech/Space Science Institute
